FallingSand visual glitch

Teleporting a falling sand block results in a delay.

Steps to reproduce 

• Place a repeating command block with the following command:

  /execute as @e[type=falling_block] at @s if block ~ ~-1 ~ repeating_command_block run tp @s ~ ~-2 ~

• Place a falling block above it and observe that it gets solid over the command block and there is a delay before it gets teleported below. This delay changes depending on the length of the drop.
